Cerbera V8 front uprights

[Lefty]

Sorry, more questions.

Whats the deal with Cerbera front uprights?

Did they change from this



To this



At some point?

Are they interchangeable?

Thanks chaps

There was a recall done in 2001 due to the risk of the uprights cracking, with corrosion affected ones replaced with the Motoclan pictured version or a cover plate PU glued to the back of non-corroded original ones.

Ahhhh ok. st. Well, mine aren t corroded or cracked or anything.

Everything else just bolts up to them right?

Thanks Basil, appreciate the info!

I would expect them to have the casting number and date stamp on them (there are combinations of straight and curved top wishbone that is important too). Motaclan info on each uprights sort of explains it. The stikaflex sealant is there to stop water sitting in and around the bottom ball joint (it is everywhere). I have stripped down a lot of front uprights recently (they list as MK1 to MK4 versions in the parts list across the T car range) and the noticeable thing for me, is, there is loctite everywhere and the front bearing bolt using a 1/2 UNF Phillidas nut and loctite (I presume that someone thought that there may be heat transfer from the bearing and that the nylon may be affected).

Yes, everything should bolt up the same to the equivalent version.

The one in your pic is the early (pre '02) short top wishbone balljoint mount position with the adapter block for the pre Sep '00 AP CP5200 brake caliper. Later ones have a mix of different brake caliper mounts and the later top balljoint position which is c.20mm towards the outer face.

Outstanding, thank you

I am still struggling with this.

The new "correct" ones seem to be C0928 (right - available) and C0929 (left - NLA).

Motaclan list the Tuscan upright as C0938 for the right (NLA) and C0939 as left (available). They state that both of these are suitable for Cerbera V8.

See my problem, neither are available as a matching pair. I don't mind changing ball joints, i'd really rather not have to change my wishbones

So i'm back to thinking about just using the original cast aluminium ones. What's the deal with the little plate that was fitted to the back of some?

I found this note of the recall

https://vehicle-recall.co.uk/recall/r-2001-085

My original ally ones are in reasonable condition so i wonder if i'm over-reacting and should just fit the backing plates and be done with it?

If there's no sign of cracking then that's what the factory did with the recall.

It was last on the road in 2014 and I guess if they survived fine that long (18 years) plus another 12 years of sitting unloved then they’ll probably survive anything

Interesting numbers on that recall
